Description

GN Ship Cargo Hold Cleaning Robot is a magnetic wall-climbing robotic platform developed for cleaning and surface-maintenance work inside steel cargo holds, especially bulk carrier cargo holds. The compact robot travels directly on compatible ferromagnetic hold surfaces while the operator supervises the work remotely from a safer position.

The reference platform combines a 35 kg compact body, 50 kg rated load, 0–18 m/min travel speed, IP66 protection, a multi-axis working joint and pan-tilt video monitoring. According to the required process, it can be configured for rust-removal cleaning, physical brushing, chemical-agent spraying or airless spraying, allowing one climbing platform to support several cargo-hold maintenance tasks.

The robot is intended for steel cargo-hold surfaces where the wall material, surface geometry, corrugations, stiffeners, coating condition and access arrangement are compatible with robotic climbing. Final tooling, cleaning media, hose routing and operating parameters are confirmed according to the vessel, cargo residue and shipyard or owner maintenance procedure.

Customer Challenges

• Bulk carrier cargo holds are large enclosed steel spaces with tall vertical surfaces, structural corrugations, frames, ladders and other areas that are difficult to reach safely and consistently.
• Manual cleaning often requires workers to operate at height, on temporary access equipment or close to contaminated surfaces, increasing labor intensity and safety-management requirements.
• Cargo residues, dust, rust, scale and coating contamination can remain on large wall areas and may require repeated washing, brushing or localized surface treatment before the next cargo or maintenance stage.
• Traditional manual work can be slow because personnel and equipment must be repositioned repeatedly across wide and high hold surfaces.
• Cleaning quality may vary with operator position, access angle and fatigue, making consistent coverage more difficult over large internal steel surfaces.
• Short vessel turnaround or shipyard maintenance windows increase the value of a remotely operated solution that can improve access and standardize repetitive wall-cleaning work.

GN Ship Cargo Hold Cleaning Robotic Solution

The robot is positioned on a compatible steel cargo-hold surface and uses magnetic wall-climbing mobility to travel across vertical or inclined areas. The operator controls the robot remotely and monitors the work through the onboard pan-tilt camera, reducing the need for continuous personnel exposure directly on the working surface.

A multi-axis working joint provides reference movement of horizontal ±90°, pitch -10° to 30° and roll ±150°, helping the end tool maintain a suitable working orientation. The 50 kg rated load allows project-specific cleaning or treatment modules to be evaluated, including rust-removal cleaning, physical brushing, chemical-agent spraying and airless spraying.

For each project, GN Smart Control reviews the vessel type, cargo-hold layout, steel material, corrugations, stiffeners, ladders, coating condition, contamination type and required cleaning process. The robot, working tool, tether or hose management, camera, control method and secondary safety arrangement are then configured as one coordinated cargo-hold cleaning solution.

Key Features & Advantages

• Magnetic Wall-Climbing Mobility: Designed for compatible ferromagnetic steel cargo-hold surfaces, allowing the robot to work directly on large vertical and inclined internal walls.
• Compact 35 kg Platform: The compact reference body supports easier deployment and repositioning inside cargo holds while providing a 50 kg rated load for working modules.
• 0–18 m/min Adjustable Travel Speed: Travel speed can be selected according to positioning, inspection, brushing, spraying or other process requirements.
• Multi-Axis Working Joint: Reference joint movement of horizontal ±90°, pitch -10° to 30° and roll ±150° provides flexible orientation for different cleaning and treatment tools.
• Pan-Tilt Video Monitoring: The onboard pan-tilt camera supports remote observation of robot travel, tool position and the local condition of the working surface.
• IP66 Protection: The reference protection rating supports demanding industrial cleaning environments where dust and water exposure must be considered.
• Multiple Cleaning Processes: The platform can be configured for rust-removal cleaning, physical brushing, chemical-agent spraying or airless spraying according to the project requirement.
• Remote Operation: Operators can supervise the robot from a safer control position, reducing continuous direct exposure to high or difficult-to-access cargo-hold surfaces.
• Modular Working Platform: The rated payload and tool interface allow the robot to be adapted to different cargo-hold cleaning and surface-maintenance tasks rather than being limited to one fixed process.

Frequently Asked Questions

Can the robot work in every ship cargo hold?

No. The working surface must provide sufficient magnetic adhesion and suitable geometry. Steel material, coating, corrugations, structural members, obstacles and access points should be reviewed before selection.

What is the robot travel speed?

The reference platform has an adjustable travel speed of 0–18 m/min. Actual working speed depends on the selected cleaning process, tool, surface condition, hose routing and project safety limits.

What cleaning processes can the robot perform?

The reference product material lists rust-removal cleaning, physical brushing, chemical-agent spraying and airless spraying. The final end tool and process parameters must be confirmed according to the cargo residue and maintenance requirement.

How flexible is the working joint?

The reference joint range is horizontal ±90°, pitch -10° to 30° and roll ±150°. This provides flexible tool orientation, but the usable range depends on the installed end module and nearby structure.

Does the robot provide video monitoring?

Yes. The reference configuration includes a pan-tilt camera for remote video monitoring of robot movement and the local working area.

Can the robot cross cargo-hold corrugations, frames or large stiffeners?

The supplied benchmark material does not specify an obstacle-crossing value for this model. Corrugations, stiffeners, welds and structural transitions should therefore be reviewed from drawings or site measurements before confirming a travel route.

Is secondary fall protection still required?

Yes. Magnetic adhesion should not be treated as the complete safety system. A suitable secondary anti-drop arrangement, tether management and project-specific recovery method should be incorporated into the vessel or shipyard operating plan.
